Update...
issued at 657 PM CST Sat Feb 28 2015

Precipitation has mostly moved into northwest Minnesota and was moving east about
20 knots. Precipitation should move out of the forecast area by midnight.
Updated probability of precipitation to reflect current movement. Tweaked hourly temperatures and
winds with colder air moving in from the west and winds shift more
west/northwest.

Short term...(this evening through Sunday night)
issued at 310 PM CST Sat Feb 28 2015

The main challenge will be temperatures and light snow chances. Models
continue in good agreement...and the GFS has done well lately.

For tonight...some cooling will move in from the W/NW...although
winds will remain up a bit...so it won't get too cold. There will
be an area of light snow/flurries that should move into northwest Minnesota
through the evening. Any accumulations will be very light though.

On Sunday...a band of middle clouds and perhaps some flurries should
affect the area. Otherwise...temperatures should be very similar to today.

Long term...(monday through saturday)
issued at 310 PM CST Sat Feb 28 2015

For Monday...moisture return will move into the south and
southerly winds will increase. It should become windy by afternoon
along with increasing clouds.

For Monday night...the threat for light snow will move along and
east of the valley. There will be strong middle level warm air advection and some
saturation...so there could be perhaps up to an inch by Tuesday
morning. A strong cold front will move into the north/northwest after 06z Tuesday.

On Tuesday...strong low level cold air advection is expected with about 35kt to
mix from 925 mb. Expect a windy and cold day with temperatures likely
steady or falling through the day with dangerous wind chills
developing by evening.

Tuesday night through Friday...another round of cold air will push
across the area Tuesday night behind a strong cold front. Cold air advection behind
boundary will make Wednesday and Thursday mornings the coldest of
the week. Otherwise...the upper ridge rebounds by the end of the
period...with gusty SW winds and thickness values indicating
temperatures approaching the freezing mark. Little precipitation is forecast
through the end of the period.
